One of the great tragedies of animal conservation is that a lot of animals are threatened with extinction -- the death of the last of them, causing their species to forever become absent from the face of the earth. Remarkable animals like the Carolina parakeet, the Aurochs, the Dodo, and the Moa, are extinct, and will never be seen again. Anything relying on them is also gone. And anything that relies on that goes away quite quickly too. Some of them have surviving relatives, like the modern Cow's relationship to the Aurochs, the Ostritch to the moa, and the nicobar pigeon to the Dodo. One scientist is aiming to change that:
Essentially, the extinct species will, from what few remaining scraps we have of their DNA, be cloned into a genetically modified parent. A modified chicken will birth small extinct birds, a modified cow will produce extinct bovines, and what was once gone forever, will cease to be gone. The first generation of these will be sickly, as the modification process has certain complications, but their children will turn out normally. And then the cold hand of death will have to release it's hand on certain animals.
Or to put it more mad-scientistly, IT'S ALIVE, IT'S ALIVE, MAKE MY CREATION LIVE!!!!
